Title: Improvements in and relating to supplying ammunition to automatic guns
Inventor: VICKERS ROY GILBERT
IPC: F41A9/54
Filed: 1957-04-16
Abstract: 848,857. Automatic guns. BREVETS AERO-MECANIQUES S. A. April 2, 1958 [April 16, 1957], No. 12389/57. Class 92. Guiding apparatus for lead ing a belt of pivotally inter linked rounds 7 to an auto matic gun comprises a fixed supply member coaxial with and leading into a funnel 8 that rotates with the gun about an extension of the trunnion axis x-x and a pair of guide bars 16 and 17 or the supply member, one above and one below the path of the belt through the funnel tc allow it to twist whilst aligning it on the axis x - x. Each belt link comprises a double clip 6a with two spaced C-shaped fingers embracing one round pivoted to a single clip 6b with one finger similarly embracing the next round. The two parts of each clip have a limited freedom of relative angular movement of + 20 degrees so that over four successive rounds the belt may twist 80 degrees. A conduit 5 leads the ,belt from a magazine 4, which traverses with but does not elevate with the gun and supplies it to the funnel 8. The belt is then pulled by a sprocket 9 into a channel 10 which houses pairs of cartridge guide-ribs 13 and 14 and a non-return pawl 12 and thence over a sprocket 11 to the gun breech. As the gun is elevated or depressed from the horizontal position shown in Fig. 1 to its maximum or minimum angles of elevation the belt is twisted to accommodate its entry into the channel 10 by the convergent form of the funnel 8. This form, illustrated in Fig. 3 in plan, is defined by a pair of plates 8c and 8d symmetrically inclined to meet the upper and lower lips of the channel entrance and bounded by cylindrical walls 8a and 8b of different radii which are tapered to join the sides of the channel entrance. Fig. 2 shows, at 7a to 7e, five successive rounds when the belt is twisted for feed at maximum elevation. In cross-section the bars 16 and 17 have a working face at 95 degrees to that used in Fig. 2. This other face accommodates the twist necessary for a small angle of depression of the gun.

Title: Acoustic transducer including piezo-electric driving element
IPC: H04R17/00
Filed: 1973-03-16
Abstract: 1399766 Piezoelectric transducers MOTOROLA Inc 16 March 1973 [10 April 1972] 12834/73 Heading H4J An electromechanical transducer such as a loud-speaker or microphone comprises a planar piezoelectric element 16 (Fig. 1), preferably disc shaped, having electrodes which when energized drive the element in a planar bending mode. When appropriately energized, first overtone nodal lines (e.g. nodal circles) are present on a major surface of the element 16. A conical diaphragm 13 having a truncated apex defining a generally circular area with a diameter less than the distance between nodes of the first overtone is attached to the element 16 to reduce the output of the first overtone so that an approximately flat response is obtained in the frequency range embracing the fundamental and first overtone. The diaphragm's truncated apex is enclosed by and substantially centered within the first overtone nodal lines. Preferably the piezoelectric element 16 includes two piezoelectric wafers 40, 41 (Fig. 4) with electrodes 42, 43, 44 on each side of each wafer. A damping member 17 of natural or synthetic rubber is fixed to the element 16 on the side opposite the diaphragm 13 and lowers the fundamental resonance frequency while damping the resonance peaks. Preferably the damping member 17 has a shear modulus which increases with increasing frequency and in the region of a centre supported resonance of the driver (1kHz) and the fundamental (5kHz) introduces hysteresis losses which substantially reduce the resonance peaks. Around the first harmonic (19kHz) the damping member 17 appears hard and hysteresis losses are substantially reduced. To compensate for reduction in hysteresis losses, iron or lead particles 46 are mixed with the material of the damping member 17, e.g. in a 3 : 1 ratio by weight. Graphite may also be added to the damping member to increase the damping action. Alternatively by using an appropriate elastomer, such as neoprene, addition of particles to compensate for reduction in hysteresis losses is unnecessary. The mass of the damping member 17 improves the coupling between the driver 15 and the diaphragm 13 and it may be desirable to add heavy particles to the member 17 to increase the mass of the driver 15. By selection of the diameter, thickness and mass of the damping member 17 the flat low frequency response of the transducer can be extended. Member 17 may be of annular form, high frequency damping being controlled by the size of the inside diameter. The cavity 12 in the housing 11 may have an undesired resonance and this may be substantially eliminated by an annular member of foam rubber.

Title: Improvements in and relating to governing mechanism for elastic fluid engines
IPC: F01D17/26
Filed: 1935-05-01
Abstract: 442,705. Fluid-pressure servomotorcontrol systems. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London. May 1, 1935, No. 13025. Convention date, May 3, 1934. [Class 135] A governing mechanism for elastic-fluid engines including speed-correcting means of the type disclosed in Specification 262,133, [Class 135], and 361,537, [Group XXVI], is provided with means for accelerating the operation of the correcting means in response to sudden increases in speed to prevent the emergency trip operating. The speed governor 27 operates a pilot valve 24 controlling the supply of pressure fluid to a servo-motor 16 which through the lever 14 pivoted about the point 29 actuates the admission valve 11 of the engine or turbine 10, and also the follow-up sleeve 22 of the pilot valve 24. The lever 14 through linkages 43, 42 and 41 operates a second pilot valve 40 controlling a servo-motor 30 which constitutes a speedcorrecting means and moves the valve 11 farther to correct the speed through the lever 14, which now pivots about its connection to the rod 15 of the servo-motor 16, and at the same time restores the sleeve 22 of the main pilot valve 24 to its original position, the pilot valve 24 also assuming its original position as the speed correction takes effect. In the event of a sudden increase of speed, this correcting mechanism may not act sufficiently fast and to accelerate its action a valve 46 is provided in a conduit leading to the servo-motor 30 which is operated by links 43, 42, and 50 from the lever 14 to supply pressurefluid direct to the servo-motor in addition to that past the pilot valve 40. The link 43 is adjustable along the lever 14 to adjust the amount of correction of the servo-motor 30 for either zero, positive, or negative regulation of the speed. Specification 422,579, [Group XXVI], also is referred to.

Title: Improvements relating to machines for turning semi-circular grooves
IPC: B23B5/10
Filed: 1952-05-22
Abstract: 705,889. Copy-turning. BECKER, H. May 22, 1952 [June 16, 1951], No. 13030/52. Class 83 (3) In a machine for turning semi-circular grooves in rolls &c. a tool-holder rotates about a vertical axis through the centre of the groove section and during this circular feed is given an additional rotational movement in the opposite sense about a vertical axis passing through the tip of the tool. A cross-slide 7 on a carriage 6 has an upstanding cylindrical portion 8, Fig. 3, which carries a rotatable base 9 for the toolholder. Rotational movement of the base to give the circular motion to the tool 22 is effected by worm and wormwheel 10, 10<SP>1</SP>, the worm shaft being driven by a feed shaft of the machine. The circular tool rest 18 is also rotatably carried about a pivot 19 forming part of an adjustable slide 20 arranged on the upper face of the base piece 9. The pivot 19 allows rotation about a vertical axis through the tool point so that the tool may be rotated about this axis in the opposite sense to its normal rotation in cutting a roll groove 2. This additional movement enables the tool-holder to be of robust construction without fouling the edges of the roll-groove being turned. The additional rotation about the point is obtained automatically by a ring gear 11, Fig. 3, on the pivot 8 engaging a pinion 12, the pivot 13 of which is in the base 9. A disc 14 on the upper end of the pivot 13 carries an eccentric pin 16, a roller on which engages a slot in the underside of the tool-holder 18.
